I thought the UK ranked well, I didn't realise it ranked that well.

Maybe there's something to be said for left-hand driving, I see Japan ranks very highly too. ;)

The real reason is I guess we take road safety seriously, we have strict drink-driving laws, and our driving test is genuinely difficult to pass.

I seem to remember road safety also featuring prominently throughout the primary national curriculum.

And of course, our infamous safety adverts that you never quite forget, such as: https://www.youtube.com/watch?v=mKHY69AFstE

Is this written in jest, or is there something more serious behind it? Off the top of my head, I cannot think of an obvious reason why "road handedness" (left vs right) would matter for road safety. Could it something about more people are right-handed so there is some 2nd order safety effect that I am overlooking?

Their comment was in jest, but I've wondered before if left vs right hand driving could affect safety. As you note right-handed people are more common. The countries with the highest percentages of left-handed people are around 12-13%.

In countries that drive on the right then drivers use their dominant hand for any controls that are on the inward side and their other hand for the control that are on the outward side of the driver.

Generally that means that the non-dominant hand handles exterior lighting, turn signals, windows, and locks. The dominant hand handles windshield wipers, transmission, and anything on the center console such as the climate and entertainment systems, and often also the navigation system.

In left drive counties that is mostly reversed for right-handed people, with the possible exception of the exterior lighting, turn signals, and windshield wipers. Those exceptions are the controls that are usually on stalks attached to the steering column. From what I've read sometimes manufactures use the same stalk positions in left and right drive models instead of reversing them like they do the rest of the controls.

Could dominant vs non-dominant hand for operating things on the center console make a difference? If everyone obeyed safety recommendations I'd expect it to not make enough difference to be noticeable, but not everyone obeys safety recommendations 100% of the time.

If someone for example tried to type in a destination using the on-screen keyboard on the navigation system console while driving I'd expect that they would take longer to do so if they were using their non-dominant hand, so they would be distracted longer.

Large airplanes usually have a pilot on either side of the center console, and they AFAIK take turns operating the airplane, so if it made a difference, I'd expected it to be studied by the aerospace industry. Given that I've never seen it mentioned on any of the airplane incident reports I've read, it probably isn't a big factor, and I see no reason why it would be different for cars.

Yes, it was in jest.

The US is just a big place. We drive a lot. Average annual mileage is about 13k vs 7k in the UK.

The USA don’t do very well on the deaths per km metric either.
